Hi, this is my online homework exercise. I think I did it right, but the system gives me wrong answer...
Can someone please check what I did
y=$\sqrt{x+\sqrt{x+\sqrt{x}}}$...
Thank you, I like Serena and SuperSonic4!
Question (b) I did with quotient rule:
g$^{\prime}$=$\frac{0sinx-1*cosx}{{sinx}^{2}}$=$\frac{-cosx}{{sinx}^{2}}$
but how to do it with Chain Rule? This fraction confuses me:confused:
Thank you again for helping!
Hello, I am struggling with these two questions. I think here should be used a quotient rule, but I am not sure how to proceed.
a) f(x)=sin$\frac{1}{x}$
b)g(x)=$\frac{1}{sinx}$
Can someone please help. Thanks
I finally did this problem and the answers are correct. Posting just in case anyone else is interested
cos(2t)=$\frac{31}{50}$
sin(2t)=$\frac{9\sqrt{19}}{50}$
cos(t2)=$\frac{-\sqrt{5}}{10}$
sin(t2)=$\frac{\sqrt{95}}{10}$
Hello,
I am trying to solve this. This material is not covered in my class, but I still want to know how to do it.
If cos(t)=$\frac{-9}{10}$ where $\pi$ <t<$\frac{3\pi}{2}$ find the values of
cos(2t)=
sin(2t)=
cos($\frac{t}{2}$)=
sin($\frac{t}{2}$)=
Give exact answers, do not use decimal...
Thank you! I tried your answer, but it is still wrong according to my school exercise system (we have online tool for practice questions), may be it is just a format it doesn't accept...
By the way, I am so bad at algebra, I am still confused about your simplification... where -2 and 27 came...
Hello,
I solved this exercise, but I probably did mistake in simplification...
f(x)=${\left(-2{x}^{2}+3\right)}^{4}$${\left(9{x}^{2}+7\right)}^{12}$
They asked to find derivative, so here is what I did...
